I'm looking at building a nice and powerful subwoofer to reinforce the low bass produced by my 5-channel bass reflex rendition of the German MTM configuration by Zalytron (using Axon 6S3 woofers and T1S tweeters).

Now, I don't have a whole lot of cash, so I don't really want to spend > $150 USD on the subwoofer. Leaving me with two options. Purchase a genuine subwoofer like the ACI SV12, or purchase a set of cheaper large woofers. Apex Jr is offering a surplus 12" woofer for $50. Specs:


Now, I am wondering if it is more likely for me to find something along the lines of the SV12 better or worse than several of these W12P's. I am not so worried about the specific drivers, but rather what I am most likely to find works better: woofers not really designed for the job of a subwoofer but several or a singler subwoofer.

My specific goal here is powerful, but controlled bass.. I might look at a bass reflex alignment because of the good results I have had with them in the past.

Edit: Graphs for wrong driver were included.

To be honest with you, I doubt you'll get a commercial unit of reasonable quality for $150 or less.

Building a sub opens up a whole new world of opportunity. If you want to reinforce the 30->40 hz region, then perhaps a 10 inch driver would be suitable. But if you want to go deeper and use a 12 inch driver, expect to pay at least 100 bucks for the driver, another 150+ for the amp, and at least 50 bucks (this can vary depending on where you live) for the enclosure. The specs for the drivers you've shown seem ok, but we have no idea what materials they're made out of. The power handling seems relatively low, and for all we know it could be a flimsy paper cone and thin foam surround. Also, that box design seems to be less than ideal for the drivers mentioned. A better one could be easily designed with a program like win ISD. If your willing to spend about 300 bucks, you can build a sub of good sound and quality, excluding little details like enclosure finish, etc. Personally, there are few commercial subs I've heard for under $1000 (exluding some of the Mirage subs I've heard) that I would consider tolerable for high end audio. Hope this helps.
